A high speed VLSI architecture for scaleable ATM switches

This paper presents a prototype of a VLSI chip to be used as a building block for an efficiently scaleable ATM switch with a link speed of 622.2 Mb/s. The chip is a 4/spl times/4 shared multibuffer ATM switch based on the distributing banyan architecture. It is efficient in storage space like a shared memory switch and scaleable in size like a space division switch. Since the architecture is self-routing, the chip contains all necessary routing control. Special high speed and low power circuitry is used. The chip is implemented in 1.0 micron static CMOS and measures only 25 mm/sup 2/ in area.
